The building that once stood here on the corner of Greenwich and Vestry Streets in Tribeca, below, doesn’t look fancy. It was probably just a regular walk-up with six or eight apartments in what had been a neighborhood of light industry for most of the 20th century.

But it sure left a formidable impression.

I love the sloping roof on this long-gone building on Washington Place in the Meatpacking District, below. Was it a garage? Warehouse? Meat packager?

I have no idea when it went down, but it’s being obliterated forever in favor of another restaurant or boutique or luxury hotel.

On 31st Street near Fifth Avenue is the imprint of a sturdy chimney and a roof on a slight incline. A coat of paint almost covers most of it up, but a sliver remains of what was once someone’s home.

The best thing about this bulldozed building on East 29th Street? The phantom smoke coming out of the pattern of a chimney!
